Wilco [ tickets ] continues to build its summer trek, adding new dates to a headlining tour that now looks set to keep the band on the road through late August.

The Chicago-based act, led by singer/guitarist Jeff Tweedy, will kick off the run July 25 way up north in Fairbanks, AK, the first of two shows outside the contiguous US, before returning in early August for a hometown appearance at the Aug. 1-3 Lollapalooza Festival. Dates are below.

Wilco continues to tour behind "Sky Blue Sky," its seventh studio album. The set, which follows 2004's "A Ghost is Born," was recorded and self-produced by the band in its own Chicago studio, with TJ Doherty (Sonic Youth, The Hold Steady) handling recording chores and Jim Scott (The Red Hot Chili Peppers, Dixie Chicks) doing the mixing.

The album arrived on The Billboard 200 album chart in the No. 4 spot, marking the band's highest debut ever, and selling 87,000 copies in the US during its first week.

The set helped Wilco nab its fourth Grammy nomination in December, receiving a nod in the Best Rock Album category (it lost out to Foo Fighters' "Echoes, Silence, Patience & Grace"). The band, which has now received four Grammy nominations overall, scored two trophies with 2004's "A Ghost is Born," which took home wins for Alternative Rock Album and Best Recording Package.

According to a recent interview with Wilco guitarist Nels Cline published in Madison, WI's Capital Times newspaper, the group plans to enter a recording studio to begin work on material a new studio album, but Cline didn't know if any of the new material would be unveiled during the band's summer road trip.

"It's not up to me," Cline told the interviewer.
